Answer:
3 1/4 lbs
Step-by-step explanation:
4 1/4 + 3 1/2 = 7 3/4
11 - 7 3/4 = 3 1/4
If you break it down into decimals it will look like this...
4.25 + 3.50 = 7.75
11 - 7.75 = 3.25
Answer:
The zeros are x=1, x=-6
Step-by-step explanation:
f(x) =x^2+5x-6
Factor: What two numbers multiply to -6 and add to 5
-1 *6 = -6
-1 +6 = 5
f(x) = (x-1) (x+6)
Using the zero product property
0 = (x-1) (x+6)
x-1 =0 x+6=0
x=1 x=-6
The zeros are x=1, x=-6
In this situation,
n=50, p=1/20, q=(1-p)=19/20, and npq=19/8=2.4
We would like np and npq to be a large number, at least greater than 10.
The normal approximation can always be applied, but the result will be very approximate, depending on the values of np and npq.
Situations are favourable for the normal approximation when p is around 0.5, say between 0.3 and 0.7, and n>30.
"Normal approximation" is using normal probability distribution to approximate the binomial distribution, when n is large (greater than 70) or exceeds the capacity of most hand-held calculators. The binomial distribution can be used if the following conditions are met:
1. Bernoulli trials, i.e. exactly two possible outcomes.2. Number of trials is known before and constant throughout the experiment, i.e. independent of outcomes.3. All trials are independent of each other.4. Probability of success is known, and remain constant throughout trials.
If all criteria are satisfied, we can model with binomial distribution, where the probability of x successes out of N trials each with probability of success p is given byP(x)=C(N,x)(p^x)(1-p)^(N-x)and,C(N,x) is number of combinations of selecting x objects out of N.
The mean is np, and variance is npq.
For the given situation, np=2.5, npq=2.375, so standard deviation=sqrt(2.375)=1.54.
D = S x T (Distance = Speed x Time)
S = D / T
T = D / S
When I need to drive to a neighboring state for my job, I look on maps
and find out how far away my destination is, and then use this formula
to calculate how long it will take me to get there, how fast I need to drive
in order to get there in the amount of time I have, how far I can get in the
time I have if I drive only at safe and legal speed, and what time I need to
head back in order to get home in time for dinner..
F = 1.8C + 32
C = 0.55 (F - 32)
These are the formulas to convert between Fahrenheit and Celsius expressions
of temperature. I use them when I'm discussing the weather with my daughter
in Israel, or with my customers almost anywhere outside the USA.
F = M x G
Weight = Mass x Gravity
This formula deals with the relationship between mass and weight. It's
used when you need to calculate the weight of some particular mass on
some particular planet. I use it almost every day, when I'm answering
questions in the Physics department on Brainly, and trying to explain
my answers.
